We discuss the major challenges in silicon ingot production for solar applications, particularly optimizing production yield, reducing costs, and improving efficiency to meet the continued high demand for solar cells. We review solar cell technology developments in recent years and the new trends.
Solar grade silicon can be produced from quartz following a two-stage process consisting of the production of metallurgic silicon and its further purification up to solar grade quality. The two most used processes are Siemens and Fluidized Bed Reactor, FBR, from Union Carbide. Siemens process was patented by Siemens Corporation in the 1950's.
The production of silicon solar cells The production of a typical silicon solar cell ( Fig. 2) starts with the carbothermic reduction of silicates in an electric arc furnace. In this process large amounts of electrical energy break the silicon–oxygen bond in SiO 2 via an endothermic reaction with carbon.
Thus, the development of optimized processes for production of cheap Si (SG) feedstock material can allow better competitivity. Solar grade silicon can be produced from quartz following a two-stage process consisting of the production of metallurgic silicon and its further purification up to solar grade quality.
However, challenges remain in several aspects, such as increasing the production yield, stability, reliability, cost, and sustainability. In this paper, we present an overview of the silicon solar cell value chain (from silicon feedstock production to ingots and solar cell processing).
Only very recently has the industry grown to the point where intermediate products, such as solar grade silicon, solar silicon wafers, solar cells and solar panels are commodities having global market potential.
